PEA-THRESHER.

SPECIFICATION forming part of Letters Patent No. 600,794, dated March15, 1898. A li ti fl d August 31,1397. Serial ITO-650,096. (N model.)

To aZZ whom it may concern:

Be it known that we,FREDERIoK W. MILLER and WARREN O.WILLrs, citizensofthe United States, residing at De Witt, in the county of Arkansas andState of Arkansas, have invented certain new and useful Improvements inPea-Threshers; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention is a pea-thresher; and the novel and advantageous featuresof the same are set out in the following specification and claim theretoattached.

In the accompanying drawings, Figure 1 is a side elevation of ourinvention. Fig. 2 is a top plan view. Fig. 3 is a longitudinal sectionalview. Fig. 4 is a top plan view of the machine after the hopper has beenremoved. Fig. 5 is a detail view of the fan-blades.

Our invention is described as follows:

1 is the frame.

2 is a body.

3 is the drive-wheel.

4 is the pulley on the shaft 1 of the fan A.

5 is a bearing for the shaft of the fan, there being another bearingexactly similar on the opposite side of the body.

6 is the band.

7 is a dust-opening, there being a similar opening on the opposite sideof the body.

8 are cleats between which the hopper 9 fits.

10 is the front incline, inclining backward and downward, throwing thepeas upon the cylinder 11'. 12 is another incline extending backward anddownward, throwing the peas upon the bottom 13, from which they aredrawn by the hand or small rake into the opening between the twoinclines, whence The cylinder cry with teeth 14, which pass betweencorresponding teeth 15 in the concave base 16. Attached to the front endof concave base 16 is a concave perforated plate 17. Said concave basehas attached to its lower end and rear side a wing 18, and said base 16is pivoted in place by means of screws 19, which pass through the bodyof the frame and into the perforations 20 of said base.

Under the cylinder 11 and at the front end of the machine is an incline21, which leads down to an opening 22, and just beyond said opening isanother incline 23, which leads down to the bottom of the body.

The object of having the base 16 pivoted, as described, by means of thescrews 19 is to adjust the base so as to accommodate the machine tolarge or small pea-pods, as they do not always grow the same size, beinglarger some years than others and growing larger on some soils than onother soils the same year. I

When the lower part of the base is thrown forward, the space betweenits. upper end and the periphery of the cylinder 11 is greater andallows a larger pea-pod to enter, and when so adjusted the rear end ofthe wing 18 is thrown a little down and gives greater force to thecurrent of air produced by the fan, and at the same time the forwardedge of the perforated plate 17 is thrown a little up and diminishes thespace between its inner upper periphery and the periphery of thecylinder, and thus, though the current is a little stronger to blow outthe hull, this position of the plate induces the pea with more certaintyto pass through the perforations of the plate.

Immediately under theopening 22 is the spout 24, which discharges thecleanpeas at the side of the machine.

The construction of our fan we believe to be entirely new. It consistsof. the shaft 1, the pulley, and the two sheets of metal 25 and 26. 25has recesses 27, and 26 an opening 28. Sheet25 is bent at the dottedline 29 at right angles, and sheet 26 is bent at rightangles on the line30. Then the part or'neck 31 is passed through the opening 28, and thenthe shaft 4 is passed in between the neck 31 and necks 32, and thus thefan is complete without the use of a nail or a screw to put the wings onthe shaft. The shaft may be either square or round.

The operation of the pea-huller is apparent.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The combination of the frame 1, body 2, hopper 9, band-wheel 3, cylinder11, having teeth 14; adjustable concave base 16, having IOO teeth 15;wing 18, secured to the lower end and front face of the base 16;perforated concave plate 17, secured to the lower end and rear face ofconcave adjustable base 16; hand 6, pulley 4, fan-wheel A, anddischarge-spout 24, substantially as shown and described and for thepurposes set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
